Warnalert11: redirect

All of a sudden, on almost every web page, Firefox is redirecting to a pop-up telling me that something is out of date or something else needs attention to be able to browse properly. Very annoying.

The URL that it's from is warnalert11.com - A web search found a site for this name that didn't help, a few other sites related to it, but no information about this gets on your system or how to get rid of it.
